Last modified Jun 16, 2026

CVE-2002-0666 is a vulnerability of currently unknown severity. IPSEC implementations including (1) FreeS/WAN and (2) KAME do not properly calculate the length of authentication data, which allows remote attackers to cause a denial of service (kernel panic) via spoofed, short Encapsulating Security Payload (ESP) packets, which result in integer signedness errors.. EPSS estimates a 2.47% chance of exploitation in the next 30 days.
